I used the fantastic pattern by Michelle of City House Studio after seeing it pattern tested by my friend Jen earlier this year. The boys asked their teachers (and my little guy's kinder teacher aide, who is pretty much a second teacher) what their favorite colours were, and went with that. The paper piecing was heaps of fun - I always enjoy using my scraps for these kinds of projects :o)
I did deviate from the pattern for the backs (due to massive time constraints, mainly!!) - rather than a pieced book shelf I just used a solid piece of fabric, and straight line quilted it.
I'm happy with how they turned out - I'm at that nervous point now of 'will they like them?'.
Now these are done, I can finally get back to bee blocks, pattern testing and QAL blocks. And Christmas, can't forget that ;o)
